OEIS Sequences

Number of length 2+3 0..n arrays with some disjoint pairs in every consecutive four terms having the same sum. A247534

a(0)=1; thereafter a(n) = 3·a(n-1) with digits rearranged into nonincreasing order. A321541

Given a distribution of n balls, labeled 1,...,n, among n unlabeled contents-ordered urns, arrange the nonempty urns in increasing order of their initial elements: U₁,...U_k and sum the quantities (i-1)(card U_i - 1) for i=1,...,k to get the "weight" of this distribution. These numbers represent the number of distributions of even weight minus the number with odd weight. A89656

a(1) = 27846; thereafter a(n+1) = a(n) # n, where # is an operation that cycles through division, addition, subtraction and multiplication. A327962
